Reduction of pollutant emissions from the combustion of hard coal after the addition of smokeless coal

Abstract

The water boiler was fed with hard coal or smokeless coal-contg. mixts. in mass ratios of 85/15 and 70/30. The compn. of exhaust gases was analyzed for the content of CO, CO2, NOx, SO2, PM2.5, PM10 and polycyclic aromatic hydrocarbons. A significant redn. of emission factors was obsd. during the combustion of blends with smokeless coal as compared to the combustion of hard coal.
